It looks like Prince Louis was very bold in the latest royal photo

Prince Louis is a little monkey.

The photos released to mark the 70th birthday of Prince Charles have caused great excitement among royal fans over the last couple of days. There have been a number of theories about the royal family's body language which you can see here but one eagle-eyed royal fan spotted something very interesting about the youngest member. If you look closely at both photos, you can see that Duchess Kate is holding her baby son's arm in the second shot and as one Twitter user suspects, this could be because Prince Louis was being a little naughty. As you'll see in the below tweet, there is an expression of pure mischief in the first snap and then in the second, Kate held his hand which *could* be because he was pulling his grandfather's hair. Both very cute and very funny. Now, of course, this is just speculation but if you look at the side by side photos pictured below, the fan in question might be on to something.

The second pic seems like the one when Louis pulled Prince Charles' hair! That about explains Kate holding his hand in the other photo.

The Twitter account, Tea Time with the Cambridges, is a very popular one and previously spotted Prince Louis making an appearance with his parents. It looks like Prince Louis could be just as cheeky as his older brother, Prince George, in the years to come. The royal children including Princess Charlotte have provided us with some laughs recently, see here for the best side-eye ever. and here's hoping they continue bringing the lols.
